Characterizing Liposomes for Drug Delivery
Researchers examine the application and usefulness of nanoparticle tracking analysis and dynamic light scattering techniques in the characterization of liposomes used as drug delivery vehicles.

Liposomes are fast becoming a preferred vehicle for delivering therapeutic drug molecules to target sites – meaning techniques to measure the size, concentration and zeta potential of the preparation are growing in importance
For a drug delivery vehicle to be successful, it will ideally localise and target the therapeutic agent to the site of interest and enable a measurable drug interaction with the affected tissue. Used increasingly for this purpose are liposomes, whose applications now include both systemic and topical drug delivery. With the capacity for formulation as liquids, solids or semi-solids, liposomes are being used in treatments ranging from targeting fungal infections to hepatitis A and acute lymphoblastic leukaemia.
